MACHINE FOR ATTACHING STRINGS T O TAGS. ENVELOPE FLAPS, AND THE LEKE.

Application filed Febi'uary 18, 1922. Serial No. 537,477.

T 0 (LU 107107;]. if may concern:

Be it known that I, GEORGE W. SWIFT, J r., a citizen of the United States, residing at Bordentown, in the county of Burlington and State of New Jersey, have made certain new and useful Improvements in Machines for Attaching Strings to Tags, Envelope Flaps, and the like, of which the following is a specification.

The invention relates to novel and'use ful improvements in machines for fastening strings and eyelets to tags, envelope flaps and the like, and more especially to novel and useful improvements in that type of machine in which the string is preliminarily looped about the eyelet position preparatory tofasteni-ng. g g

Objects and advantages 'of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described. g g

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

, Fig. 9 is a top Fig. 8; V g g I Fig. 10 is a side elevation, looking at Fig. 9 from the right, with the bed plate in section, and g 4 Fig. 11 is fragmentary, somewhat diagrammatic view of the washer 'attachlng and eyeleti ng mechanisms.

\ Fig. 12 is a fragmentary axial sectionen plan corresponding to an enlarged scale showing advanced positions of certain operating parts shown in Fig. 11.

The invention is directed to improvements in machines for affixing strings to paper tags, envelope flaps and the like, and is directed more especially to a novel mechanism for presenting the string between the tag or envelope flap and reenforcing strip or piece (paper washers being an example), an eyelet being then upset through the reenforcing piece, or pieces, andthe tag or flap so as to firmly hold the string in position.

The invention is embodied in a machine of the general type or kind which is shown and described in United States Patent No. 96,125 to William Liddell, dated October 26, 1869, wherein a string is automatically looped preliminarily about the eyelet position, the eyelet plunger then being driven through the loop and the eyelet being thereby upset, and a predetermined length of the spring is cut off, and there is then a new feed of the string for the next stringing operation.

Ob ects of the invention are to provide string looping means which except at the moment of string attaching are located well away and separate from the washer attaching and the eyelet attaching means, so as to provide ample space and to avoid obstruction of those means, leaving them free and open for inspection and adjustment, for

clearing out of any jammed material or for any other purposes; to provide for continuous retention of the string by the looping means to avoid the necessity of cum brous and uncertain mechanism for conveying the string to the looping means after each tag or flap stringing operation: to provide string cutting means which will not cut the string between the string supply and the looping means, thereby contributing to simplicity of structure and certainty of op eration in the machine: to provide for forming a loose loop in the free or loose end of a string and moving the loop to and presenting it at the place of fastening only at the moment of fastening the string, washer and eyelet to the flap or tag, at other times maintaining the looping mechanism and the washer presenting and eyeleting mechanism well spaced away from each other. In addition to the foregoing, the invention provides an exceedingly simple and highly efficient and very reliable loop forming mechanism, useful in the described relation and in other relations as well. therobjects and advantages of the invention will be set forth in connection with the following detailed description of the invention.

Referring now in detail to the present preferred embodiment of the invention, il lustrated by way of example in the accom panying drawings, and referring first to the means for forming the loose loop in the free end of the string, said means comprise, or are in cooperation and association with, mechanism for continuously retaining hold and control of the string supply, and also with mechanism for traveling the loop to the eyeleting' and washer fastening position, and then moving it away again ust previous to fastening the eyelet. The operation in many respects is analogous to the old method used by hand, or manually by the workman, in which the workman gave a turn to the string about the eyelet die plunger, his hand approaching merely for this operation and then moving away from the mechanism.

In said embodied form, the traveling carrier 1 is shown as an arm oscillating to and fro with a shaft 2 to which the arm is fixed. The drive for the looping mechanism is operated by this movement of the carrier 1 to and from the eyeleting and washer ailixing position.

hfieans are provided on the traveling carrier 1 for holding the string a so that it is carried forward in fixed relation to the loop forming mechanism when the latter is trav eling toward the eyeleting and washer arlixing position, and for causing it to run through the mechanism of the carrier 1 when it is receding from that position, so that a desired length of string will be provided attached to the tag or envelope flap, and so that this length can be cut off between the eyelcting mechanism and the loop-forming mechanism, thereby making it possible for the looping mechanism to continuously rctain hold of the string from the string supply.

In the embodied form of string holding and controlling means, an extension 5 projects laterally from the bottom end of the arm 1. and fixed thereon is a block 6, hav ing formed therein an aperture 7 through which the string (4 passes. Adjacent the apertured block 6 is a flat spring 8 fixed to the block by screws 9, the spring having a recess 10 therein. The string passes from aperture 7 v the recess 10, and then passes through the recess and on beneath the spring to the loop forming mechanism.

A. supporting, guiding, and aligning device cooperating with the loop forming mechanism is provided, and as embodied, a pin 1% is fixed at 15 in the arm 1. This pin has in its bottom end a guiding aperture on the outside of the spring tov 16,-in definite and desired relation to the loopforming mechanism, as shown in Figs. 1 and 2.

In accordance with certain features of the invention, a loose loop is formed in the free end of the string, with the end of the string projecting freely from the loop, as the carrier travels toward the eyeleting and washer aflixing station, the loop being completed and presented at the eveletiug station just prior to the advance of the eyelet die plunger, which then comes in through the formed loop.

In the embodied form of said means, a fiat circular disc 20 is fixed on a hollow shaft 21 (Figs. 1, 2 and 3), journaled in the bottom part of the carrier arm 1, and fixed to the shaft 21 on the opposite side of the arm 1 is a pinion 22, which is driven to rotate the disc 20. Fixed to the periphery of the disc 20 is a string-engaging, loop forming finger 23, adapted to engage with the freeend of the string a during the rotation of the disc 20 to form the loose loop.

Cooperating with the disc 20, as embodied, is a member constituting therewith an annular, peripheral channelway in which the string is laid to form the loose loop,

and as embodied. a conoidal disc 24c, which is also concentrically hollow. and alined with hollow shaft against the outer flat face of the disc 20.

lhis member is resiliently pressed against the face of the disc 20, to form the channelway as described and so that at the proper time it may move away to release the loose loop in turning it about the eyelet die plunger and' then return to position for forming the next loop. For this purpose, the disc 24. is mounted on a fiat spring 27, fixed by suitable means such as screws 28, to a part of the carrier arm 1.

For the purpose of traveling the carrier 1 forward to present the loose loop at the eveleting and washer-affixing station and then immediately traveling the loop forming mechanism backward away therefrom prior to the eyeleting and washer aiiixiug operation, the disc 24. the disc 20. the pinion 22 and the shaft 21 are laterally recessed as shown at 30 in Fig. 1 and Fig. 8. thereby permitting the t *aveling carrier arm to move away after the eyelet die plunger has passed through the loose loop.

In the embodied form of means for so swinging the carrier arm 1 to and fro toward and away from the eyelet-mg position and for actuating the loop-forming mechanism during this travel of the carrier. a gear wheel is fixed on a shaft 10, journaled in the lower part of the carrier arm 1, (Figs. 1 and 3) the shaft lO having a retaining collar 41 on the opposite side of the arm 1. The gear wheel 39 is in mesh with the pinion 22, and is rotated periodically as shown at 26, presses a predetermined distance, so as to cause the loop forming mechanism to form the loop.

In mesh with gear wheel 40 is an idler gear 44, fixed on a shaft 45, journaled in the arm 1 and having fixed thereto a retaining collar 46 on the opposite side of the arm 1. Meshing with gear wheel 44 is a pinion 47, lixed on a shaft 48, which shaft is ournaled in the arm 1. Fixed also on shaft 48 (Figs. 3, 8 and 10) is a ratchet wheel 49, with which cooperates a pawl 50, pivoted on a pin 51, which is mounted on a gear wheel 52, which gear wheel is journaled loosely on the shaft 48 on the inner side of the ratchet wheel 49.

Meshing with the gear wheel 52 is a stationary geared sector 53, loosely hung at 54 on shaft 2, and held in fixed position by a stud 55, mounted on one of the supports for shaft 2, through which a bolt 56 is screwthreaded into the sector. As a matter of construction the arm 1 is fixed by a bolt 57 v 1 means for controlling the angular movement and positioning of the gear wheel 39, and thereby of the loop-forming mechanism, there are formed in the inner face of the gear wheel 89 a plurality of detent depressions 68, spaced apart angularly on the gear wheel so that the distance between two adj acent detent depressions will effect one revolution of the loop-forming mechanism. C0- operating therewith is a spring-pressed pin 69 mounted in a detachable block 70, carried in the lowerpart of the arm 1, and in the path of the depressions 68. Pin 69 is acted on by a spring 70, resiliently pressing it against the face of the gear wheel 39.

Referring to the embodied form of means for mounting and oscillating the shaft 2. the shaft is journaled in standards 73 and 74, supported on and projecting upwardly from the machine frame (Figs. 8. 8, 9 and is an arm 75, and pivotally connected at 76 to the end of the arm is a link 77. which link at its opposite end 78 is pivotally connected to a crank disc 79 fixed on a shaft 80. Shaft 80 is journaled in bearings ,81 and 82, on the machine frame, and is provided at the other end thereof with any suitable form of drive, such as a belt pulley 83.

The manner of operation of the mechanism just.- described. is substantially as follows r Referring more especially to Figs. 1, 3 and 8, the mechanism and gearing is proportioned so that gear wheel 39 during the swing of carrier arm 1 in one direction will rotate the distance between one detent depression 68 and the next adjacent one, thereby causing one complete 0 eration of the loop-forming mechanism. .he pawl and Fixed to the opposite end of shaft 2' ratchet drive liolds the loopfmfming mechanism stationary during the travel of the carrier arm 1 in the opposite direction. During this movei'l'ient of the carrier arm with the looping mechanism idle, the desired length of string ismeasured off from the point where it is fixed under the eyelet. and it is then cut ofi between the eyelet and the loop-forming mechanism. The loop forming mechanism thus continuously keeps hold of the string from the string supply, and obviates the necessity of providing mechanism for picking up the string again after each string attaching operation and carrying it to the looping mechanism, and successfully reinserting it therein with the attendant cost, mechanical complications and uncertainty of operation.

The carrier arm 1 may be considered as in the position of Fig. 8, at its full travel away from the eyeleting position, and ready to begin its advance toward the left in Fig. 8. At this time the string a has its free end in substantially the position of Figs. 1, 2 and 4. As the arm 1 moves forward, the gearing is thereby actuated. and gear wheel 39 is started, springing pin 69 out'of the detent 68.

Pin 23 is thus rotated in clock-wise direction in Fig.1, and bends the free end of the string downwardly beneath it, laying it in the annular peripheral channel way between the discs 20 and 24. In Fig. 5, the position is shown after substantially a half revolution of the loop forming mechanism. In Fig. 6 the mechanism is shown just before the completion of the loop.

It will be noted that by reason of the relation of the parts, including the guiding aperture 16, that the free end of the string in the loose loop is brought upon the inside of the adjacent and contacting part of the string a and a complete loose loop of string is formed with the free end loosely held in position by the passing and contacting part of the loop, leaving the loose free end of the formed loop projecting outwardly as shown in Fig. 6. Just as the loop is completed, the spring pin 69 will snap into the next detent depression 68 in'gear wheel thus bringing the parts exactly into position for beginning the next looping operation.

In accordance with one feature of the invention, and as already indicated. the eyelet die plunger is inserted through the previously formedloose loop, and then the free end of the loop is grasped to draw it about the plunger, similarly to the old hand operation, and the loopforming mechanism is retracted and moves away just prior to the eyeleting and washer aflixing operation. and in fact is present and in juxtaposition with the 'eyeleting mechanism and washer presenting mechanism only during the single instant of presenting the loose loop.

So far as concerns most features of the invention, the eyeleting mechanism and the washer presentingmechanism may be of any known or desired form, and as shown herein, and referring primarily to the eyeleting mechanism, one eyelet die mechanism 95 is longitudinally reciprocably mounted in a block 96. carried on the bottom plate 97 of the machine frame. This n'iechanism is re ciproca-ted in a suitable manner, and as show, a pin 98 proiects therefrom, and

pivoted thereto is a link 99, which link is pivotally connected at 100 to a crank 101, the crank being fixed on a shaft 102, iournaled at 103 on the machine bed 97. Fixed on shaft 102 is a beveled gear 104, with which meshes a beveled gear 105, fixed on the shaft 80.

The cooperating eyeleting die mechanism, as embodied, comprises a die 110, longitudinally reciprocably mounted in a block 111 and a block 112,fixed on the machine bed 97, and likewise actuated in a suitable manner, and as embodied, a block 113 is fixed on the die plunger 110, having a recess 115 formed therein. lVorking in the recess 115 is a roller 116, rotatably carried on a shaft 117, journalled in a bearing 118, carried on the machine bed.

Fixed to the shaft 117 is a beveled gear 119, which meshes with a beveled gear 120, fixed on the shaft 80. These mechanisms operate the eyeleting punches in the usual manner. Eyeleting die 110 is provided with theusual plunger 121, and any known or other suitable supply of eyelets is provided, a well-known commercial form thereof being indicated by 123 in Fig. 10.

In accordance with certain features of the invention, reinforcing means are applied to the tag or envelope flap or the like, and these reinforcing devices are usually in the form of washers, applied to either side of the tag or flap. Any suitable form of washer supplying and presenting means may be used, so far as concerns most features of the invention, and such a mecha nism is shown in Fig. 11, for applying a washer to either side of a tag or flap. In Fig. 11, the stock a: for one washer is fed forward between rolls 126 and 127, and is presented to any suitable form of washer die 128. On the other side the washer stock is fed forward between rolls 129 and 130, and is presented to any suitable washer die 131. I I

Means are provided for grasping the free end of the string of the loose loop, and as embodied, a. shaft 138 is journaled in brackets 139 and 14:0 (Figs. 8 and 9), mounted on the bed plate 97. Fixed to or formed on one end of the rod 138 is a gripper jaw 141, which cooperates with a fixed jaw 1412, consisting of a plate mounted on the machine frame. The actuating means for jaw 14.1

comprises an arm 14-3, fixed to shaft 188. Pivotally connected to arm 143 at 1 14 is a link 1 15, which is pivoted at its other end 1 16 to a lever 1&7. Lever 1&7 is pivotally supported at 148 on a standard 1&9, fixed to the machine frame. At its opposite end lever 1 17 has a cam roll 150, cooperating with a cam 151, which is fixed on the shaft 80. ii spring 152 holds the cam roll to its cam.

li leans are provided for furnishing an adequate supply of string to the loop-forming mechanism, and, as embodied, a pair of feed rolls 160 and 161 are journaled, respectively, at 162 and 163 in standards 164- and 165, which are carried on a bracket 166, supported from the machine bed 97. One of the rollers has fixed to its shaft a belt pulley 167, over which runs a belt 168, which also runs over a pulley 169, fixed on the shaft 80. The string goes from the feed rollers to a support and guide 172, mounted on the machine frame. Thus an adequate supply of loose string is provided for the mechanism during its travel and loop-forming movements.

Means are also provided by the invention for severing the desired length of string between the eyeleting means and the loop forming means, this location and operation of the cutting means leaving the string supply in continuous engagement with, and under the continuous control of, the loop-forming mechanism.

ris embodied (Figs. 8, 9 and 10), a fixed shear blade 176 is mounted at 177 upon the machine bed. A pivoted shear blade 178 is pivotally mounted at 179 upon the machine bed. At the lower end 180 thereof, the pivoted blade 178 is pivotally connected to a link 181, which link is longitudinally reciprocably supported, and it has a cam roll 1841- working in an annular cam groove 185 formed in the hub of the pulley 169, which is fixed on the shaft 80.

The manner of operation of the mechanism just described is substantially as follows The momentary loop with its free presentation of the loose end at the eyeleting and washer supplying station has already been described, and is shown in Fig. 6. Just at this moment the eyelet die plunger 121, carrying one of the washers and the eyelet in the usual manner, passes through the central aperture 26 in the loop-forming mechanism, and at this instant the jaw 141 closes down on the free end of the string, as shown in Figs. 6 and 7.

At the same moment, the traveling carrier 1 swings backwardly to the right in Fig. 8, and as the end of the string is held in gripper 141, 14-2, the tension on the string at spring 8 will cause spring 27 and disc 24- to yield, releasing the loop, and leaving the string (5. turned once about the eyelet on die plunger 121 as shown in Fig; 7 andin the same manner as iii-the hand operation; The eyelet is upset in the usual manner. During this return movement of the carrier arm 1 to the right in Fig. 8, it Will be understood that the looping mechanism is idle and in position for the next looping operation, due to the paWl and ratchet and 51, and that the string a which is now held by the gripper 141, 142, Will run freely hrough the holding spring 10. As the carrier arm 1 gets back to the position of Fig. 8, the shears 176, 178, will cut off the desired length of string to the left of the carrier arm in' Fig. 8, and on the same side thereof as-the eyeleting mechanism. Thus the supply of string a, shown as a. loose loop. in Fig. 8, Will he in absolutely the same relation, as

regards engagement and control, to. the.

loop forming mechanism at all times, irrespective of the travel of the carrier, or of the forming oi the loop. As the. carrier moves toward the. left in Fig. 8, the spring 10 Will prevent the string from pulling out or changing its relation to the looping mechanism, and in fact there is never any strain on the loose loop 0t string which forms the reserve supply and Which 1S preterahly uniformly fed forward by the rolls 160 and 161.

The invention in its broader aspects is not limited to the speci tic mechanisms shown and; described but departures may he made therefrom Within the scope oi the accomian in claims without de artin from the.
